write a program in c language

You need to send a message to another person but don't want the information to leak in the delivery process. Your task is to encrypt the message by firstly taking the string and encrypt it using an encryption algorithm that can change the meaning string into a random string of words. Once the string is encrypted insert it into a file Hint: We can use the value of pi which can be millions of digits long considering its floating-point nature. But we can use it to our advantage, starting from the whole number try adding or subtracting the ascii value of the character in the string to encrypt the message and then continue using this approximation after the decimal point for each character. Value of pi =3.141592653589793238462643383 //Note you would not be able to store all of it Input (From File): This Text is Encrypted Output (Fo File): Wimts Wfludrual Hogs yvkiv(a) //Note you have to get the exact same message illustrated above in the file
